Automatic Transfer Switches with Manual Bypass/Isolation
The Russelectric RTS-30 Series and Russelectric RTS-03 Series transfer switches provide all the functions of a Russelectric automatic transfer switch plus the ability to bypass power from a live source to load in the event the transfer switch is disabled. Russelectric automatic transfer switches with manual bypass/isolation are the most complete line of 480 Vac 30-cycle and 3-cycle UL tested switches available today. They have been fully tested, listed, and labeled for 30-cycle and 3-cycle closing and withstand ratings under UL-1008. Full draw-out construction allows safe and easy removal of the transfer switch, eliminating the need to make any electrical or mechanical disconnections.
Built rugged for long life, minimum maintenance, and trouble-free service, the RTS-30 Series features contact assemblies designed to handle the rigors of 30-cycle closing and withstand performance and offer exceptional arc- and track-resistance. The main contact pad material is designed to prevent overheating, and stationary contact pad material prevents welding during high fault current conditions. When coordinated with current limiting fuses, Russelectric RTS-03 Series transfer switches have UL listed closing and withstand ratings of 200,000 amperes, at 480 Vac. Russelectric RTS-03 and RTS-30 Series transfer switch contacts are machined from solid copper and feature tungsten arcing tips.
